DISCHARGE MECIIANISM Eon vISIE MACHINES AND 'rIIE LIKE. i

to `discharge the piesv in whichever direction it may be desired.' s n l The ejector mechanism is substantially the same as the mechanism shown in my copending application, Serial No. 56,282, led September 14, 1925,now-tPatent No. 1,671,321, granted May 29, 1928, and the means for swinging the ejector to discharge at different Stations are shown herein.

The pie making machine is'quite large and bulky, and is usually `installed in close quarters wherein it is not always possible to set the machine to discharge in the proper direction if the ejector is fixed. Accordingly, in this invention, theV frame or base member is pivotally mounted so it may be swung in any direction.

An illustrative embodiment of this inven* tion is shown in the accompanying drawings, in which:

Fig. 1 is a plan view of the delivery end of the machine.

Fig. 2 is a side elevation of Fig. 1, with parts omittedand parts brokenaway.

Fig. 3 is a detail section of the parts mount-V ed on the vertical drive shaft, and taken as indicated by line 3 3 in Fig. 1.

The pies 1 are formed in pie tins which are placed on the supports 2 at the left side of the machine. The supports are carried by an endless conveyor built up of the jointed links 3, which are supported at either side of the machine frame 4 and are engaged on the horizontal j sprocket wheels 51, kwhich are mounted at either 'end of the frame 4.

As'the pie tins travel alongthe left side of the machine and return along lthe right side, the crusts and filler are deposited in the tins, and the crust is trimmed. The pies are then delivered from the end of the machine, whichis shown, ready for baking.

The supports 2 aremounted on the horizontal disks 5 which are mounted on the sleeves 6 in every second joint of the conveyor. A lifter disk 7 which normally rests on the disk 5, is provided with a rod 8, which is slidable in the sleeves l6 and projects from the lower end thereof. 7

In discharging, the lower end of the rod 8 rides up on the cam rail 9, which is supported below the sprocket 5, and the pie tin withv the finished lpie thereon yis lifted out-of the i support 2in position to Zbe-engaged by the and moved laterally onto the conveyor'belt 131. The sprocket wheel 5.1 is ymounted on the' vertical sha-ft 112, which is Vrotatably lsup- ,f horizontally reciprocating ejector platel'@ Y portedjby the arm v13 which is attached to fthe f machine vframe 4. Theshaft 12 is driven'by avwormon the drive shaft 14, which meshes with a worm gear A16,- secured Lon-the "lower end of the shaft 12. p

, The base 17 of the ejector rests on the` top of the .arm 13V and is pivotedV on the shaft 12. The base 17 is locked in any desired rotative position by means ofthe capv screw 18, suitable tapped holes being of course provided in the arm 13. s

The ejector plate 10 is carried onthev end of the bar 19, which is slidable in the guide member 20 which is mounted on the upwardly projecting arms 21 `of the base 17. For reciprocating the bar 19, a lever 22 is connected f at one end to a plate 23, secured on the base 17, by means of a link 24. The mid portion Y of the lever 22 is pivoted on the crank pin 25 of the crank arm 26; and the other end of the 7 lever is slidably engaged with the bar 19. i

The crank arm is keyed on a stub shaft- 26,

which is rotatably mounted in the base 17,`

and is rotated by means of the pinion 27,

keyed on the shaft, which meshes with a spur gear 28 which is keyed 0n the upper endfof the sprocket wheel shaft 12.

VSince'a pie is carried on each quadrant of `the wheel 51, the gear 28 is four times as large as the pinion 27. Thereby the ejector cocof operates with each pie support, and will register in any position the base is rotated1 after it has beenproperly timed for one position.

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that numerous vdetails of the construction'shown may be altered or omitted without departing from the spirit of this invention as definedv bythe following claims I claim: Y

1. In a pie machine, a pie conveyor mounted to move in a circular path about a fixed center, and ejector means for removing the pies from the conveyor, said means being mounted for rotation about said 'center and having a positive driving connection with the conveyor.

eno' Y 2. In a pie machine having pie supports mounted to travel in a circular path about a fixed center, ejector means cooperating with said supports to remove the pies, said means being mounted so that it may be adjustable about said center.

3. In a pie machine having pie supports` mounted to travel about a fixed center, ejector means for cooperating VWith said supports, said means being mounted for adjustment about said center and having a positive driving connection With said supports so as to register with each support in any of the adjusted positions.

4. In a pie machine having a vertical shaft and a conveyor for pie supports carried by a Wheel fixed to the shaft, an ejector support adj ustably rotatable on the shaft, a gear keyed on the sha-ft, a pinion mounted on the 'ejector support and meshed with the gear, and ejector means for removing the pies from the supports, said means being mounted onthe second mentioned support and having a positive driving connection With the pinion.

5. In a pie machine having a conveyor for a piev support` carried on a Wheel fixed to a shaft, Vejector[means for removing the pie from said-support, said means having apositive driving connection with the shaft and adj ustably pivoted thereon so that it may be set to discharge the pies in various directions. i 6. In a pie machine having a conveyor for a pie support carried on a Wheel fixed to a shaft, ejector means for removing the pie from the support, said means having a base which is adjustably supported on said shaft, and being operatively connected to the shaft.
